MACRO absolute muon flux measurement: Comparison with Monte Carlo predictions

The vertical muon intensity measured with MACRO at the Gran Sasso Laboratory, in the depth range 3200-7000 hg cm(-2) of standard rock, corresponding to 2-200 TeV/nucleon primary energy range, is presented. An estimation of the muon energy spectrum at the surface will also be shown. The results will be compared with those of other experiments and with the computation of the intensities obtained using a full Monte Carlo calculation with different hypotheses for the primary cosmic ray composition.
